Step 1: Case
1 again, it had to be cylindrical.
2 it had to be re-close able.
3 it had to be lying around the house somewhere.
a film canister was close but just a little bit too small, and i finally decided on an empty pill bottle.
Step 2: The stuff
9v adapter thing...
old pcb or strip board.
10k ohm resistor (i salvaged mine from another old pcb)
Step 4: Circutry
Step 6: LED's
Step 7: Soldering
Step 8: Drill and fit...
Step 9: Hot glue
Step 10: Head gear
those little hair band thingy's make great high durability rubber bands.
apparently they all have specific names for there's sizes! i don't think i will ever understand women
